Hello, 

Completely brand new to development, let alone with regard to SF. 

We have recently set up a Partner Community so that we can receive leads from our upstairs partner through here instead of manually typing new leads sent via email into SF. 

I've set up a sandbox for their developer upstairs to work on integrating the two but before he can get much further, he requested this "API URL endpoint" for testing, preferably in the sandbox. 

Can someone please explain to me like I'm 5 how to find this exact information for him?
